-Routine Description:
- This is the SNP interface routine for getting the NIC's statistics.
- This routine basically retrieves snp structure, checks the SNP state and
- calls the pxe_ routine to actually do the
-
-Arguments:
- this - context pointer
- ResetFlag - true to reset the NIC's statistics counters to zero.
- StatTableSizePtr - pointer to the statistics table size
- StatTablePtr - pointer to the statistics table
